stock blaster tires are 21 by 10 by 8's. I have some 20 by 10 by 8 holeshots on it now, but can i go 20 by 11 by 8's without changing the rim. in other words, can i get a wider tire without changing the rims? i know that the 8 has to stay the same

 

Yes you can.

 

so in other words the only number that has to be the same is the rim size? i just want to be sure b/c i don't want to order tires then have them not fit

 

correct as long as the other numbers are not way off the stock size. I would stay with in 1 or 2 sizes of the stock #s.

 

thanks, i was thinking 20 by 11 by 8 razr's
